DE406968C - Fastening clamp, especially for laying electrical cables - Google Patents

Description

The invention relates to a fastening clip, which is preferably used for laying electrical lines is intended, in the form that the connection between the clamp and the cable to the exclusion of screws or screw-like fasteners can be done. At the same time, with the new fastening clamp, there are protruding parts or those that are exposed to the eye

ίο special fasteners not recognizable, and the line itself is in a precisely determined position over its entire length Distance from the wall, if such a free movement is desired.

Furthermore, the new fastening clip is characterized by an advantageous mode of stress from, so that despite the small wall thickness and small material consumption, there is considerable strength. Finally is Care has also been taken to ensure that the connection between the pipe clamp and the pipe is loosened cannot occur. According to the invention, the new pipe clamp is or multi-part hollow body formed, the bottom part for direct attachment the clamp on the wall is used, while two are perpendicular to this opposite Wall parts form the bearing for the pipe to be laid by means of corresponding cutouts; perpendicular to the bearing part . Standing wall parts provide the firm connection of the pipe to the pipe clamp hollow body.

To explain the concept of the invention, an exemplary embodiment is shown in the drawing shown, namely shows:

Fig. Ι a multi-part spacer clip in a diagrammatic representation,

Fig. 2 the associated cross-section when the spacer clip is attached to a 40 ' building wall and with the insulating tube and

Fig. 3 shows the corresponding side view. the

Figs. 4, 5 and 6 contain three embodiments of a one-piece spacer clip in the representation of Fig. 1.

Fig. 7 is the modification of the embodiment according to Fig. 6 in the manner of a multi-part spacer clamp, and

Fig. 8 is a cross-section of the subject matter of the invention as a support bracket as shown of Fig. 2.

The spacer clip according to Fig. 1 to 3 consists of a lower part and an arched closing part /, thin sheet metal is assumed as the material. The lower part contains the bottom c, the perpendicular to this ascending and opposite, arcuate cut-out bearing walls α and the connecting walls b. The latter face each other, but are placed at a right angle to the bearing walls α . The connecting wall b has punched-out tabs e, to which the corresponding openings g of the striker / belong.

The assembly of an insulating tube // in which the corresponding cable runs is to be thought, takes place

means of the new device extremely easy and quick, the tube h itself runs at a precisely determined distance from the wall after its laying. In the wall z. B. wooden dowel k and the lower part of the clamp by means of a screw / which passes through a hole d , firmly screwed to the dowel k or the associated wall. The tube is then inserted into the cutouts in the bearing wall α , the striker / Jn is pushed over the tube in the manner shown in Fig. 2 and the connecting walls b are then pressed in so far that the tabs e reach through the openings g of the bracket / and. hold it down firmly on the pipe. It does not matter in what way the tabs e engage in corresponding openings g. They could, for example, be deformed by suitable tools to such an extent that they hook-shaped encompass the corresponding edges of the openings g , while in the exemplary embodiment according to FIG. 2 the tabs e simply pass through the openings and act as an abutment for the striker.

In the embodiment according to FIG. 4, the striker b ¹ , like the bearing wall α and the connecting wall b, is made in a single piece with the bottom c . The striker b ¹ is then bent around the latter after the pipe has been laid so far that the tab e ² again engages in the opening g ^{2 of} the connecting wall b . In the embodiment of Fig. 5, the striker is designed in the form of two tongues b ² , b ³ , which rise from the bottom 1 c and find a more solid connection to the latter through overlapping tabs e ^{3 of} the bearing walls α. Here, too, after the pipe has been laid, the two tongues b ² and b ³ are bent laterally over the pipe so that it has a firm,! Encompasses. '

While the embodiments described so far have a lower part with a polygonal (square) cross-section, the lower part a ^{1 of} the embodiment is! Measured in Fig. 6 held in the shape of a tube. In addition, this tubular lower part has the arch-shaped bearing cutouts and also: the connecting tongues b ² and b ^s rise from it, which surround the inserted pipe in: the manner shown in Fig. 6 ^; conclude.

In the embodiment according to FIG. 7, the spacer clip again has a special striker / whose ends, which are to be deformed accordingly, pass through openings g of the tubular lower part a ¹ in their working position.

In Fig. 8, the bearing section of the bearing wall parts α is chosen so that the pipe h to be laid by means of the clamp is located directly on the associated wall. In addition, the embodiment according to FIG. 6 is also to be thought of as being associated with the cross-section of FIG. 8, ie the locking tongues b ² and b ^s are again provided. Common to all embodiments is the fact that the material from which the hollow body of the clamp is made is sufficiently inelastic to guarantee a firm engagement of the relevant tabs and locking tongues.
